IMPORTANT! DO NOT lubricate pump tube or roller assembly. Manually rotate the roller assembly counterclockwise to align one of three roller assembly slots with the suction side housing slot.
Place tube fitting into suction side slot of the housing and the roller assembly slot. Figure E With pump setting on L, hold tube fitting and jog roller assembly by turning pump on. IMPORTANT! Avoid rotating wrist, which can result in a twisted tube that will not center. DO NOT force tube and be careful of your fingers. Guide tube with slight tension toward the center to prevent pinching between housing and roller assembly. If the tube is pinched during installation, discard. Figure F When tube reaches the discharge tube housing slot, turn pump off. Turn dial ring to setting 10, hold tube fitting firmly, do not pull, and turn pump on. NOTE: A used tube will have stretched approximately 3/4" and the new tube will appear to be stiff and short. Follow directions to allow rollers to stretch tube into place. Allow rollers to stretch tube into place while guiding tube into slot. Figure G Turn pump off. Apply a small amount of AquaShield® to cover bushing ONLY and replace cover and two screws.

Turn pump off, let go of fitting, and finger tighten cover screws. Inspect the suction and discharge lines, point of injection and check valve duckbill for blockages. Clean and/or replace as needed. Reconnect the suction and discharge lines. NOTE: Cover screws are self-tapping and must be backed in to locate original thread before securing. If a screw boss is stripped, use alternate bosses and position opposite from each other. Never secure the cover plate with more than 2 screws.

Figure C Align the center of the inverted cover with the center of the roller assembly so that the three holes on the face of the cover align with the three knurled lugs on the roller assembly. Position the cover feet near the tube fittings. Figure D NOTE: The roller assembly needs to be collapsed to remove the tube. On the adjustable pump, hold the feed rate control securely. On the fixed output pump hold the pump securely. Use the tube housing cover as a wrench and quickly (snap) rotate the cover counter-clockwise to collapse the roller assembly. The tube will no longer be pressed against the tube housing wall. Figure E NOTE: Counter-clockwise is viewed from facing the head of the pump. Remove and discard the pump tube. Figure F Remove the roller assembly, and the tube housing. On the adjustable pump also remove the shaft. Set them aside to reinstall later. Use a non-citrus all-purpose cleaner to clean chemical residue from the tube housing, roller assembly and cover. Check the housing for cracks and replace it if it is cracked. Ensure the rollers turn freely. Replace the roller assembly if the rollers are seized or worn or if there is a reduction or lack of output from the pump. Figure G Reinstall the clean tube housing. On an adjustable pump, also install the shaft into the feed rate control. Apply AquaShield® to the shaft tip. Install the roller assembly.
III INSTALL THE PUMP TUBE AND EXPAND THE ROLLER ASSEMBLY IMPORTANT! DO NOT lubricate pump tube or roller assembly. Ensure the power to the pump is off and the power cord is unplugged. On the adjustable model, ensure that the feed rate control is set to 10. Figure H
Place the new tube in the pump head; use your fingers to center it over the rollers. Figure I Place the tube housing cover on the tube housing, affix the front latches to the cover lip and then press the latches back to secure. Figure J With the cover latched, plug the pump in and turn the power on. Allow the pump to run the roller assembly in its collapsed position for approximately one minute to relax the tube. Figure K Turn the pump off and unplug the power cord. Remove the tube housing cover and flip to use as a tool in the next step. Figure L Align the center of the inverted cover with the center of the roller assembly so that the three holes on the face of the cover align with the three knurled lugs on the roller assembly. Position the cover feet near the bottom. Figure M NOTE: The roller assembly needs to be expanded so the tube is pressed against the tube housing wall. Expand roller assembly.
